Ingredients

1 1/2
pounds
portobello mushrooms, stems discarded and caps halved and sliced
1 1/2
pounds
cremini mushrooms, trimmed and sliced
1/4
cup
olive oil
1
tablespoon
fresh thyme leaves
kosher salt and black pepper
1/2
cup
(1 stick) unsalted butter, plus more for the foil
1/2
cup
all-purpose flour
6
cups
whole milk
1/4
teaspoon
ground nutmeg
1
cup
grated Parmesan (4 ounces)
12
no-boil lasagna noodles
2
10-ounce packages frozen chopped spinach, thawed and squeezed dry

Directions

  1. Heat oven to 400° F. Dividing evenly, on 2 rimmed baking sheets, toss the mushrooms with the oil, thyme, ¾ teaspoon salt, and ¼ teaspoon pepper. Roast, tossing once, until tender, 20 to 25 minutes; let cool. Reduce oven to 375° F.
  2. Meanwhile, melt the butter in a large saucepan over medium heat. Add the flour and cook, stirring, until foamy, 1 to 2 minutes (do not let the mixture darken). Slowly whisk in the milk. Bring to a simmer and cook, whisking often, until thickened, 3 to 5 minutes. Remove from heat, add the nutmeg, ½ cup of the Parmesan, ¾ teaspoon salt, and ¼ teaspoon pepper, and stir to combine.
  3. Spread ½ cup of the milk mixture in the bottom of a 9-by-13-inch baking dish. Top with 4 noodles (breaking to fit, if necessary), ½ cup of the remaining milk mixture, 1 package of the spinach, and half the mushrooms; repeat. Top with the remaining 4 noodles, milk mixture, and ½ cup of Parmesan.
  4. Cover the dish with buttered foil and bake until the filling is bubbling, 15 to 20 minutes. Uncover and bake until the noodles are tender and the top is brown, 20 to 25 minutes more. Let rest for 15 minutes before serving.
